Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out to clear, complete description.
Embodiment 1:
As shown in Figure 1, the slot measurement device that the utility model embodiment provides, comprises base 1, dwang 2 and lifter 3.The stiff end of dwang 2 is flexibly connected with base 1, specifically can connect by modes such as rotating shafts.The free end of dwang 2 and lifter 3 are in transmission connection, and in the present embodiment, the free end of dwang 2 is overlapped on the end of lifter 3, and when lifter 3 moves up and down, the free end of dwang 2 just can rotate around stiff end.
As shown in Figure 2, the slot measurement device that the utility model embodiment provides can be used for measuring the size in the gap between liquid crystal panel 4 and chase 5.In addition, this slot measurement device also can be used for measuring liquid crystal panel in liquid crystal display or LCD TV and the gap between shell etc.
When carrying out the measurement in gap, the initial position of lifter 3 is extreme lower position, dwang 2 is attached on base 1, and the stiff end of dwang 2 is stretched in gap together with base 1, and be close to the lower edge in gap.Then lifter 3 is started, the free end of dwang 2 is rotated around stiff end, when the body of rod of dwang 2 touch gap upper along time, by lifter 3 brakings.
As shown in Figures 2 and 3, before lifter 3 starts, can first record the distance L between lifter 3 and stiff end, after lifter 3 brakings, record again the height S that lifter 3 rises, so just can calculate the now included angle A of dwang 2 and base 1 formation according to tan tanA=S/L.Record the contact point a on edge on dwang 2 and gap and the distance l between stiff end again, just can calculate the distance s between a point and base according to sine function sinA=s/l, s is the width in gap.
Therefore, the slot measurement device that the utility model embodiment provides only needs single job just can record accurately the size in gap, do not need examination repeatedly to survey, and according to length everywhere, by trigonometric function, calculate the size in gap in the present embodiment, guarantee the precision of measuring, thereby solved the low and measuring accuracy low technical matters of the measurement efficiency of existing slot measurement method.
Embodiment 2:
The present embodiment is substantially the same manner as Example 1, its difference is: as shown in Figure 4, in the present embodiment, dwang 2 is telescopic rod, and the free end of dwang 2 is fixed on to the end of lifter 3 by rotating shaft, being connected between the free end that makes dwang 2 and lifter 3 is more firm, and when lifter 3 rises, dwang 2 can extend, the length needs while rotating to meet.
Further, on lifter 3, be provided with pressure transducer 31.When dwang 2 is in rotation process, while contacting with the upper edge in gap, on gap, resistance will be caused to the rotation of dwang 2 in edge, pressure transducer 31 on lifter 3 can pass through this resistance of dwang 2 perception, the soon lifter 3 of existing side by side is braked, to guarantee that dwang 2 can forward position accurately to, thereby guarantee the accuracy of measurement.
Further, base 1 is for being with graduated scale, and the zero graduation of scale is positioned at the stiff end place of dwang 2.When measuring the size in gap, before starting lifter 3, can first according to actual conditions, adjust the horizontal level of lifter 3.After the horizontal position adjustment of lifter 3 is complete, just can utilize the scale on base 1, read easily the distance between lifter 3 and the stiff end of dwang 2.
Because the situation in measured gap is different, so before starting lifter 3, can, by adjusting the horizontal level of lifter 3, make to there is comparatively suitable distance between lifter 3 and the stiff end of dwang 2, to adapt to current measured gap.
Further, be provided with height sensor (not shown) on lifter 3, this height sensor can be arranged on the end of lifter 3, can be specifically infrared ray height sensor etc.After lifter 3 brakings, just can directly measure the height that lifter 3 rises by height sensor.
As shown in Figure 4, the slot measurement device that the present embodiment provides, further can also comprise computing machine 6, and this computing machine 6 is connected with height sensor.After lifter 3 brakings, height sensor just can directly be inputted measured height in computing machine 6, so that the follow-up trigonometric function operation of computing machine 6.Certainly, before lifter 3 starts, the distance between measured lifter 3 and the stiff end of dwang 2, also can input in computing machine 6 in advance.
As shown in Figure 4, in the present embodiment, be further also provided with slide block 21 and driver (not shown) on dwang 2, driver drives slide block 21 moves along dwang 2.The initial position of slide block 21 can be arranged on the stiff end of dwang 21, at dwang 2, touch the upper edge in gap, after stopping operating, just can be by driver drives slide block 21, move to the contact point place on edge on dwang 2 and gap, and obtain 21 the displacement of sliding, i.e. distance between contact point and stiff end.In addition, driver also can be connected with lifter 3, when lifter 3 braking, just starts immediately driver, drives slide block 21 to move up.
Further, on driver, be provided with displacement transducer (not shown).For example, driver can adopt gear type driver or rotary shaft driver, and the number of turns that displacement transducer only needs perception gear or rotating shaft to rotate just can be obtained the displacement of slide block 21.This displacement transducer also can be connected with computing machine 6, so that the displacement of slide block 21 is inputted in computing machine 6, so that the follow-up trigonometric function operation of computing machine 6.
As shown in Fig. 5 and Fig. 3, the slot measurement device that the utility model embodiment provides, when carrying out the measurement in gap, first lifter 3, dwang 2 and slide block 21 are resetted, then after the stiff end of dwang 2 being stretched in gap together with base 1, the horizontal level of adjusting lifter 3, records the distance L between lifter 3 and stiff end, and L is inputted in computing machine 6.If measurement in batches, need to can in computing machine 6, not preserve the value of L in the situation that all adjust the horizontal level of lifter 3 in each measurement, while just not needing to measure again at every turn all to computing machine 6 input L.
Then lifter 3 is started, the free end of dwang 2 is rotated around stiff end, in rotation process, telescopic dwang 2 can extend.When the body of rod of dwang 2 touch gap upper along time, the pressure transducer 31 on lifter 3 can perceive on gap along the resistance to dwang 2 effects, is about to lifter 3 brakings for thirty years of age, starts driver simultaneously, drives slide block 21 to move up along dwang 2.Now, the height S input computing machine 6 that the height sensor on lifter 3 can rise lifter 3.
When slide block 21 moves to the contact point a on edge on dwang 2 and gap, will stop moving, the displacement l input computing machine 6 that the displacement transducer on driver moves slide block 21, l is the distance between a point and stiff end.
Now, computing machine 6 just can be according to L and the S of input before, and utilizes tan tanA=S/L to calculate the included angle A that dwang and base form, then according to before the l that inputs, and utilizing sine function sinA=s/l to calculate the distance s between a point and base, s is the width in gap.
Therefore, the slot measurement device that the utility model embodiment provides can complete automatically by parts such as lifter, driver, computing machines the measurement of gap size, and do not need examination repeatedly to survey, and in the present embodiment by computing machine according to length everywhere, and utilize trigonometric function to calculate the size in gap, guarantee the precision of measuring, thereby solved the low and measuring accuracy low technical matters of the measurement efficiency of existing slot measurement method.
The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
